OCA Java SE 8 Programmer Certification Crash Course, Part 2

Your full Oracle Certified Associate Certification Resource

Simon Roberts

This class is Part 2 of OCA Java SE 8 Programmer Certification Crash Course, Part 1. Certification can be a valuable distinguishing feature for your resume, and if you’re looking for credibility as a Java programmer, Oracle’s is the certification you mostly likely will pursue. The certification is the most recent in a long line of exams originated by the presenter of this course while he worked at Sun Microsystems, and has a reputation for being challenging. This class is a live presentation of the presenter’s well-received video training on the same topic. In it, you’ll have the chance to augment your learning by asking questions and discussing details with other learners in the Group Chat.

It’s probably fair to observe that a majority of programmers work from day to day with just a little more knowledge of the languages they work with than is needed to get their immediate job done. We tend to learn new features when existing code uses them. While undeniably pragmatic, it’s beneficial to have a more solid understanding than this, and even if you aren’t pursuing the certification, this class can be beneficial in providing that.

What you'll learn-and how you can apply it

This course will address all the objectives of the Oracle Certified Associate, Java SE 8 Programmer exam. The objectives are listed on the Oracle website:

This training course is for you because...

  • You’re a Java programmer intending to take the certification exam
  • You’re a software engineer with skills in another object oriented language (particularly the C/C++ derived family) looking to move into Java programming
  • You’re a beginning to mid-level Java programmer looking to build and solidify your skills in the language
  • You’re a college student looking for additional learning resources to help you with a Java course you’re taking

Prerequisites

This course seeks to minimize prerequisites so as to be as accessible as possible, however, you should be reasonably comfortable reading simple code written in the Java programming language

Materials, downloads, or Supplemental Content needed in advance:

While not required for participation, it’s a good idea if you have a Java development environment (e.g. NetBeans, Eclipse, Intelli-J IDEA or similar) so that you can experiment with the material you learn in the class.

Resources:

Source code repository on github.com will be used to distribute examples and other materials created during the course

Recommended Prep:

Java Programming Basics: This course provides an introduction the Java Programming Language and would be particularly appropriate for anyone with minimal background in Java before attending this live training.

OCA Java SE 8 Programmer (1Z0-808) Complete Video Course:This course addresses, in detail, all the objectives of the exam and this live training and may be used before or after the live class to prepare, or reinforce and act as reference for the material learned.

About your instructor

  • Simon started out working as a software engineer, specializing in industrial control systems, and had a sideline teaching for a local University in his then-home-town of Cambridge, England.

    In 1995 he joined Sun Microsystems, Inc. as a senior instructor and course developer. Simon spearheaded the introduction of Java training by Sun Microsystems in the U.K. in 1995. He developed the first Java certification exams for Sun before he moved to the U.S. in 1998.

    Since leaving Sun in 2004, Simon has developed and delivered training for clients around the world.

    Simon believes that training should have an immediate purpose and application, and that the most effective training is usually "on the job" mentoring, helping to remove the immediate roadblocks to productivity that so often plague workers in fast moving environments.
